So far, it seems only Muslim women from abroad dare lead men in Friday prayers in the UK. A Canadian, Raheel Raza, became the second Muslim woman to do so at the Muslim Educational Centre in Oxford last week. An African-American convert, Amina Wadud, was the first Muslim woman to lead mixed prayers at the same centre in 2008. It's not surprising that British Muslim women are not brave enough to follow their footsteps – both have been demonised after leading men in prayers in their own countries.

Why is the idea of female imams so controversial amongst many Muslims? When Amina Wadud shocked the world in 2005 by leading mixed-gender Friday prayers in New York, I must admit even I felt uncomfortable. I had been brought up to believe only men could be imams, something I never questioned until recently.

An honest study of Islamic texts reveals that women are not forbidden to lead men in prayer – the Qur'an does not even address this issue. In fact the conditions required are Islamic knowledge, skill and piety – none of which are gender related. However, (mostly male) scholars maintain there is consensus on the impermissibility of women leading men in prayer despite lack of evidence to back up their position. In many quarters, this issue is not even open to debate, despite the fact that centuries ago it was discussed without controversy and a diversity of opinions was respected. According to female scholar Halima Krausen, a number of male scholars, such as Abu Thawr al-Kalbi, Abu Isma'il al-Muzani, al-Isfahani, at-Tabari and Ibn Taymiyya, had nothing against women leading mixed prayers. One woman, Umm Waraqa, is known to have led men in prayers in her household during the time of Prophet Muhammad.

Male clergy often cite questionable hadiths or take them out of context to criticise women such as Wadud. One argument often marshalled is that women's bodily movements arousing desires in men. Are men really so weak that they can't keep their eyes off a fully covered woman's posterior during prayer? I believe men have invented arguments about their sexual excitement – it is only their ego that prevents them from praying behind a woman.

Despite these powerful arguments supporting the permissibility of women leading mixed congregation prayers, I doubt the practice will become widespread in the near future as religious institutions are controlled by men. And most Muslim women are more concerned about fighting for equality on basic grounds such as education and economic empowerment. I don't think leading prayers is a battle that many are yet ready to fight, even if they believe in it. But Wadud and Raza are paving the way for more female imams to come forward to lead other women in prayer. Last year Hawaria Fattah became the first female imam in Europe after being recruited to a mosque in Belgium. This is a pioneering appointment even though she only works with Muslim women.

Restricting women's role in religious structures and practices is not exclusive to Islam. Historically all the world's major religions have done this. The first female rabbi was Regina Jonas, who was only ordained privately in 1935 in Berlin. The next ordination came in the US, in 1972, when Sally Priesand was made a rabbi in the Reform tradition. Since then, all branches of Judaism, except Orthodoxy, have found a way to ordain women.

Female priests may have been ordained in various branches of Christianity. However, its largest denomination, Roman Catholicism, has consistently refused to allow women into the priesthood. Those ordained unofficially are often excommunicated. This status quo continues to be challenged – last week a group marched to St Peter's Square demanding a debate on this issue. Opening the doors to the priesthood would mean women could ascend to the papacy – and perhaps the possibility of a future female pope is too much for the Catholic church.

Women are suffering the consequences of oppressive misinterpretations of religious texts in all faiths. It's time more of us questioned their legitimacy. No topic should be out of bounds for discussion, including the question of female religious leaders. The act of attempting to break down the last barriers to female participation sends an unequivocal message about equality.
